equivalent of objdump for dex files - dex

Question

Is there any equivalent to objdump for dex files?
I don't want to decompile them, just be able to watch their content

Answer 1

Just in case it helps someone in the future:
$ sudo apt install dexdump

Answer 2

baksmali has a dump command that generates an annotated hex dump of a dex file
baksmali dump helloworld.dex > helloworld.txt

It is also able to list the items in some of the various constant pools
baksmali list classes helloworld.dex
LHelloWorld;
baksmali list methods helloworld.dex
LHelloWorld;->main([Ljava/lang/String;)V
Ljava/io/PrintStream;->println(Ljava/lang/String;)V
baksmali list fields helloworld.dex
Ljava/lang/System;->out:Ljava/io/PrintStream;
baksmali list strings helloworld.dex
"Hello World!"
"LHelloWorld;"
"Ljava/io/PrintStream;"
"Ljava/lang/Object;"
"Ljava/lang/String;"
"Ljava/lang/System;"
"V"
"VL"
